Results: Successful placement was achieved in 95.8% (567/592) cases with a median time of 9 minutes. Children younger than 2 years were less likely to have success on the first attempt (38.9% vs 53.5%) and have longer time to success (11 minutes).

Conclusions: Children younger than 2 years experienced lower first-attempt successful PIV placement and took longer. The overall success rate was similar to prior reports; these data are the first to show differential PIV success by patient age.
